The New York Mets are a professional baseball team based in the borough of Queens in New York City. They play in Major League Baseball's National League East Division. One of baseball's first expansion teams, the Mets were founded in 1962 to replace New York's departed National League teams, the New York Giants and Brooklyn Dodgers. The Mets' colors are composed of the Dodgers' blue and Giants' orange. During the 1962 and 1963 seasons, the Mets played their home games at the Polo Grounds. From 1964 to 2008, the Mets' home ballpark was Shea Stadium. In 2009, they moved into a new ballpark, Citi Field.
